UNITED STATES PATENT OFFICE! CHARLES O. MYERS AND HOWARD '1. MAKING, OF GETTYSBURG. PENNSYLVANIA.

PUNCTURE-PROOF AUTOMOBILE-TIRE SUPPORTER.

Specification of Letters Patent.

Patented July 4, 1916.

for the wheels of automobiles and the like,

and the primary object of the invention is to provide a simple, durable, and efficient construction of puncture-proof automobile tire supporter which can be easily insert-- ed within the tire shoe or casing and interposed between the same and the inner tube, and which will effectually prevent the inner tube from becoming punctured, while at the same time it will tend to support the same and promote the resilience of the tire and insure the easy riding of the car.

A further object of the invention is a device of this'character, the parts of which are constructed and arranged that the inner tube will not only be fully protected from punctures, but also from other 1njuries, and which will notdetract from the resilience of the inner tube or tend to injure it in any way. And the invention also aims to generally improve automobile tires so as to render them more useful and commercially desirable.- V V With these and other ob ects in v1ew,= as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the partsthat we shall hereinafter more fully describe and claim;

For a full understanding of the invention, reference is tobe had to the following description and accompanyingi drawing, in which,

Figure 1 is-a transverse sectional ylew showing our device in posltion within a pneumatic tire, and Fig. 2 is a fragmentary outer face or plan view of the device detached.

Corresponding and hke parts are referred to in the following description and designated in all of the views ofvthe accompanying drawing by like reference characters.

Referring to the drawing, the numeral 1 designates an annular member which is designed to extend circumferentially around the tire and between the shoe or casing and the inner tube, as shown, said member bemgconstructed in the present instance of an lnner ply or section 2 and an outer ply vor section 3 arranged in superposed and concentric relation to each other and secured together in any desired way. In the present lnstance, stitching 4 is used, the line of stitching extending medially of the two piles or sections, but it is to be understood that the invention is not limited thereto but that any desired or suitable means may be employed to secure the two plies together.

It will be noted that by having the plies or sections 2 and 3 united at medial points or more particularly at their transverse centers, the marginal portions thereofare capable of separating movement and this in practice isof material import as it will be at once perceived that in the event the outer ply or section 3 should be pierced, the penetrating article will be deflected by the inner ply or section 2, especially in view of the fact that the plies are capable of a certain degree of flexure as thesame are preferably of'sole leather which, as is .well known, is very tough and which will render the tire practicallyv puncture proof. These plies ezrtend entirely around the tire, as above in dicated, and are tapered at their ends where they are designed to overlap, whereby the entire device is of a uniform thickness throughout and the' ends are permitted to give as the tire becomes more or less inflated.

It is to be understood that the annular member 1 is held within the tire by an at taching member 5 which ma Y be formed of canvas or any other suitab e substance or material and which may have its side edges secured together by lacing (i or by any other desired means. The annular member 1 is secured to the attaching member 5 in any desired manner, stitching 7 being shown as employed in the present instance. and preferably, in order to avoid any sharp edges at the sides of the inner ply 2, said side edges preferably have secured thereto. by stitching or any other means, overlapping bindings 8 of soft leather or some other suitable substance.

In order to further protect the inner tube, the attaching member 5 has secured tilt etc by stitching or otherwise, an inner liuiu 1 1) of some. relatively soft material such as cotton flannel, felt or the like, said in b the lacing although it is to be under-- I p reel u (led.

" made 1n the-' 'con'str' u ing being; folded lonfg'itiuliually to afi'ord a' plurality of superimposed plies of a transverse width in excess of the-major trans verse diameter of theflanmilar member 1.

From the foregoing. deseript'imr-in conneetion with .theaecompanyingdrawing, the

operation ofoitr im rored punetureproof automolnle tire supporter will be apparent. In the praetiealuse of-the device, It is mterposed between the inner tube and the outer shoe or easing, and is secured i 'n plaee stood that other means mar be employed for .this purpose, as hereinbefore stated. Thus,

it,'\\'ill be understood that the tire illvn'otonly beu'ell sup1')m-ted.-but all-liabilit of its becmning punctured-(rill;be positively It is .tob'e particularly noted that no rivets or any other metal parts are embodied in-the construction; which would Q11;- v proportions of the parts without departing from the scopeof theinvention as defined in the appended claims either the angeinent. and

In the preferred mode of manufacture of our device, the leather is soaked and oper, ated upon by A I I press.

What re claim, is 2: i

1. An internal armor foripneumatiotires eompri'sing an annular member gmbodving inner and outer concentricsuperposed plies,

said plies being secured one'-t-o'the other at substantially their transverse center-sand in a eireumferential' direction; 'the portions of the phesat-{op -iosites des of the conneetjon being capable of'relative separating movement. F 1

'1. in internal armor for pneumatictires. comprising an annular member embodying inner andouter concentricsuperposed plies,

said plies being secured one-to the other at substantiallytheir transverse centers and in a circtnnferent ial direction, the portions 01- a hydraulic] or other heav v the plies at opposite sides-oftheconnection Y being capableofrelative' separating'movement,' and lHQflllS carried by the inner ply.

for maintaining, the armor in applied posi-" tion , In test-intone whereof ire a-fiix our 'signat u res in p resenceof two witnesses. I
